Description

Technical Field

[0001] The utility model belongs to the technical field of thermal runaway monitoring, and in particular relates to an extended thermal runaway monitor. Background Art

[0002] Thermal runaway monitoring is a technology used to detect, monitor and manage thermal runaway conditions in equipment or systems. Thermal runaway refers to the inability to effectively control or discharge heat in a device or system, which may lead to overheating, combustion or other dangerous conditions. This monitoring technology usually uses sensors to monitor temperature, pressure and other related parameters in real time to detect and prevent potential thermal runaway events in a timely manner. Thermal runaway monitoring technology can better understand the working status of the equipment and take timely measures to prevent accidents, thereby improving the reliability and safety of the equipment.

[0003] A Chinese patent with application number 202021384916.9 discloses an air suction device for a nanoparticle detector and an active nanoparticle detector, comprising a shell, an air cavity arranged inside the shell, a gas collection component arranged on the shell, and an exhaust component; the output end of the gas collection component is connected to the input end of the air cavity; the output end of the air cavity is connected to the input end of the gas exhaust component; by setting the air cavity, the output end of the gas collection component is collected in the air cavity, and a part of the gas is sampled and transported to the next chamber for analysis during the transmission process, and the other part of the gas is collected in the air cavity and discharged through the exhaust component, and the gas output of each collection point is collected in the air cavity. When collecting the gas at a certain collection point, the gas at another collection point can fill the gas vacancy in the shell, preventing the exhaust component from having to constantly change the exhaust speed, thereby ensuring the balance of the airflow in the shell, high gas unobstructedness, faster gas transmission speed, and longer collection distance.
